After the tea talk,
"Brother Yu truly lives up to the reputation of a great power from the Heavenly World. Listening to a single conversation with you is better than reading ten years' worth of books. If I weren't worried about you misunderstanding, I'd truly wish to spend my days and nights in your company, even sharing the same pillow. However, should I encounter any confusion in the future, I humbly ask that you do not skimp on your guidance."
Yu Xian's words were polite, presenting an eagerness to learn.
Yu Yuan remained calm and spoke indifferently, "Knowledge has its price, and although I currently possess nothing of value, I am willing to exchange with you."
Yu Yuan understood Yu Xian's intent and also why he was allowed to continue living freely, unrestrained, and able to pursue his cultivation.
Though he no longer had his previous cultivation realm, his knowledge remained intact.
For Yu Xian, a native of this land, higher-level knowledge was a treasure beyond price.
